Application led April 10, 1914. Serial No. 831,068.

To aZZ whom it may concern Be it known that I, LA MARCUS A. THOMP- soN,a citizen of the United States, residing at New York, county of NewYork, and State of New York, have invented a new and useful Improvementin Safety Devices for Pleasure-Railway Cars, of which the following is afull, clear, and exact description,

force. It is, therefore, advisable to provide means for locking theriders iii their seats. This has been done by providing a safety devicecomprising a pivoted handle bar which may be swung forwardly to allowriders to enter the carfand assume their seats yand then swingrearwardly to bring the bar into position in front of the trunks andabove the legs of the riders. Means have been provided to secure thesafety de 'ice inl locking position and also to release the same toallow the riders to enter and leave the car.` The object of my inventionis to provide new and improved locking means accomplishing the resultsabove set forth whichy will have certain advantages over known means inrespect to simplicity of construction and operation and unlikelihood ofgetting out of order and in respect to its possession of otheradvantages and functions, all of which will be more fully understood byreference to the particular description in connection with the drawings,in which:

Figure l is a perspective view of the track, loading and unloadingstations, and cams for releasing safety device. Fig. 2 is a sectionalperspective view o-f part of a car with safety devices applied thereto.Figs. 3 and 4 are side elevations, respectively in locked and unlockedposition, of the safety device. a is the loading station, b theunloading station, c the' track,"and Z the car. The safety device is inthe form of a yoke comprising the cross bar c and arms f, f, each of thelattei being pivotally mounted between vertically extending guide platesg, g, within, and projecting from the rear wall of, a casing i securedto the car body.

Within the channel formeel between the guide plates g, g slides alocking bar z'. The

upper end of the channel is closed by a crosspiece or stop m, while across-piece or stop n connects the lower ends of the guide plates and isadapted to limit the downward movemeant of the bar z' by engaging aprojection j on the bar. y

The upper end of the bar/Z is widened to form a cam 7c which is widestat its top and tapers downward and thence extends abruptly inward toform a shoulder Z. The

pivoted end of the arm f is also enlarged to form an upwardly andinwardly projecting Zhen the bar is held in a raised position, the arm 7is free to move forward and up ward on its pivot, the high point of thecam 'o passing under the shoulder Z. Or if the Vbar is liftedsubstantially above its lowest position, but not to its extreme upperposition, the cam o will act upon cani 7c to raise Athe bar z' to itseXtreme upper position and allow the high point of the Cain 0 to rideunder the shoulder Z. As the arm f is completing its movement into itseXtreme upper or forward position, the high point of the rcam o movesslightly downward in an inclined direction, allowing the spring cushionor spring p, between the upper end of bar z' `and the stop m, to movethe bar c' slightly downward, thus releasably holding the arm f in itsupward oi` forward position, but per-` mitting it to be depressed withthe exercise of moderate manual force.

When the yoke e f is swung downward and rearward into its lockingposition, the

bar i, unless otherwise upheld, drops until the lproject-ion '7' abutsagainst the stopy n, placing the cam 7c in such position that it actsas-a stop against the campo to prevent the arm f from being swung upwardand forward.

Each bar z' extends downward beneath the car-body and is in alinementwith cams s, t, arranged along the track. One pair of cams is providedat the loading station and another pair at the unloading station.

Let it be assumed that the car is' traveling along the course and thatthe yoke c f has been swung into position to lock the occupants in theirseats, and that each bar i has dropped so as to prevent the yoke e fbars z' sufficiently high to allow the yoke e f to be swung intoposition to free the passengers. So long as the car remains at theunloading station, the yoke c f can be freely l swung in eitherdirection. In the travel of l lower ends of bars z' engage cams t,which,y like cams s, lift the bars z' high enough to the car. from theloading station to the unloading station, the bars z' pass beyond thecams s, If the yoke e f has been moved into its unlocking position, itremains in that position owing to the downward pressure of the shoulderZ against the cam 0i. If

the yoke e f has been moved into its lock-A ing position, the bars a'drop as soon as they pass beyond cam s, thereby locking the yoke in itslocking position.V When the car reaches or nears the loading station,the

permit the return of the yoke e f into position to allow ready ingressto the cars. So long as the car remains at the loading station, the yoke'e f is freely movable from either position to the other. Before the carstarts, the attendant swings the yoke e f into position to retain thepassengers in their seats and as soon as bars z', in thev 'startingmovement of the car, move beyond cams t, the bars drop and lock the yokefrom being swung into its unloading position.

yoke e f and the locking bar Having now fully described my invention;what I claim and desire to protect by Let-l' ters Patent is-- l.
